for the 'purposeof illustration I have shown an embodiment of my invention in the form of a shaving brush, the device may comprise ahollovv substantially tubular body portion 1' and a ferrule 2 holding. the usual bristles 3. As clearly illustrated, the upper end of the body'l is slightlytapered as also is the ferrule 2 which is adapted to fit snugly over the rubber valve car- With referenceto thedrawings, in which the correspondingly tapered end of the-body and to beretained thereon'by thefrictional contactbetween these parts. I The brushfurther comprises as a partof the casing or housing a tapered retaining ring 4 which fits over a correspondingly tapered lower end of the body 1 andfunccontainer 5, such as shown in Fig. 4, which is adapted to be inserted within the bodyl.

Aswith the ferrule 2, the frictionalengagement' of the tapered parts of the retaining ring 4 "and the body 1 are relied upon to For reasons herelnafter .made clear,"it; is

tions to retain, in an operable position, a

from rotational movement in thecasing 1,

andfor this purpose I provide atthe top of the casing a polygonal or other irregularly "shaped projection 6'formed in the pres ent instance as an integral part of the body 1, and at the upper end of the container 5 i I provide a co'rre'spondingly shaped extenwhich projects. downwardly below the con-1 sion 7 which fits Within the part 6 of the casing. The container 5 further comprises above the part 7 a nozzle portion 8 which is provided with a discharge port 9 at 'its upper end and is adapted to project upwardly through the base of the bristles, as clearly illustrate'd'in Fig. 5, when the" parts are assembled. Projecting from the bottom of the container 5 is an operating member 10 by means of which, as hereinafter described, any desired portion ofthe contents of the container may be expelled into the body of the bristles, and the ring member 4 is so shaped as to provide free access to this actuating member while retaining the container 5 in the casing 1.

. Referring toFigs. 5 to. 12, inclusive. .the

container 5 comprises a cylindrical shell 11 havingat the top a cap 12 which. includes the part 7 and the no'zzle 8. In the bottom of the casing is secured a lo'ckingmember 13 tainer and which comprises, asbest shown in i Fig. 6, transversely exteu'ding and oppositely .inclined wings 14,14. The member. 13 is longitudinally apertured for reception of the lower end of a threaded stem 15 axially aligned with, and lying within, the interior ofthe shell 11, said stem having secured to the end thereof which projects beyondthe member 13 the operating member '10, best shown in Fig. 7, which constitutes a means for rotating the stem and which is ,also ,adaptedto cooperate with the inclined wings shown in Fig. 11 which is adapted, to retain thereon a rubber or other suitable valve.

member17. The cap'16 is in the'iform of a .fiat plate having ears 18 punched out of the plate and turned over so as to grip the sides of the rubber valve element 1 7, as shown in The member 10 which is substantiallyin the form of a hollow cylinder is provided with a diametrical slot or opening 19 of suflicient width to permit the passage into its interior of the wing members 140i the part 13. When therefore the member 10 with the stem is-forced inwardly of the shellll to the position shown in Fig.5so that themember 13 enters through the opening 19, the valve 17 is brought tightly against the hole 9, and

when thereforethe actuating member 10 is rotated to the right, see Figs. 6 and 7, it

ridesup on the inclined wings 14,14, and thereby still further moves the stein 15 inwardly and brings the valve 17 even more tightly against the port 9, thereby insuring a tight closure and also looking the stem in this port-closing position. v

The container or cartridge also comprises inside of .the shell a plunger which in the present instance includesa metal disk-2O to which is attached a rubber or other suitable disk 21,: themetal disk 20 in the present in-' stance having, as shownin; Fig. 8, pressed out tongues 22 which function to hold the rubber disk against the face .ofthe metal disk. Thismetal disk is loosely supported upon a sleeve 23- on, the stem 15, having,

threaded engagement with the latter by reason of inward projections 24 at the top and bottom edges which engage the threads. oi the stem. The sleeve has an outwardly extending fflange .25 at one end and is turned over as shown at 26 at the otherend to pre-' vent the plunger from passing off the sleeve while'permitting the plunger and the sleeve a certain; axial relative movement. To prevent relative rotational movementot the plunger and the'sleeve, the latter is provlded w th a longitudinal ridge ortongue-27 which fits into a corresp'onding recess 28 in the'centre bore of the metal disk 20.

Withrhe 'aforedescribed construction, op-

ei'ation ofthe device is as follows Assumingthat the stem 15 1s 1n theadvanced or port-closing position as previously.

describedand as shown in Fig. 5,: a partial turnof the element 10to' the left brings'the wings 14 of the locking element13 into registry' with the opening tliemember 10 v and permits' the latter member {with the stem 15 to drawndownwardly until pressed-out tongues thereon engage the inner endof the locking element 13. This uncovers the port 9. It will be noted that.

axial movementofthe stem 15 does not afieet the plunger 20-21, since the" sleeve 23' 1s "axially 'slidable" with respect to the plunger.

With the parts in this position, rotation of t the member 10 and the stein15 to the right eiiect'a a movement of the sleeve 23 toward the discharge end of the container until the flange 25 engages the underside of the plunger 2021, after which a continued r0- tational movement of the stem 15 advances the plunger andeirpels the containedmate rial, in 'thepresent instance shaving soap in a plasticfor semi-liquid state,'t'rom the uncovered port 9. When sufficient soap has been expelled, the meinber 10 with the stem 15 is rotated to the left or in reverse direction whlch has the effect oi causlng'the sleeve 23 to be retracted on the stem, the plunger 2021 however, 'i'emaining' stationaryby reason of the free relative movement between the plunger and the. sleeve.

After the sleeve has moved until the turnedover flange 26'engages the disk 20 of the plunger and with the member 10in position in whichthe'wings 14, 14, of the member 13 are againin registry-with the opening 19,-the member withthestem-lfi may be moved inwardly of the container, thereby bringing the valve 17 against the inner side of the port9. A partial'rotationof the member 10 in a right hand direction results in the cooperative action of the inclined wings 14, 14, and the said member '10 'to force the stem inwardly so that the valve of the ring 4 as indicated in Fig. 5, thereby 17 bears against and tightly closes the port 9 and so that the stem is locked in this portclosmg position. i

A material advantage in this construction resides in the extreme simplicity of the de-. vice and the low cost of manufacture. A

further material advantage resides in the fact that the mechanism by which the ma terial is expelled from the container or cartridge constitutes a part of the cartridge 5 and is such as to provide for a positive sealing oi the container during the period of time that the brush is not in use.

It will be noted that the retaining ring 4 at the bottom of the casing extends below i the end of the container 5, and that the member 10 when in the locked position of the stem lies within the plane of the lower edge threaded engagement with the plunger and projecting through one end of the shell, the

' inner end of said stem constituting a valve for closing the discharge port of the container and the stem being axially movable in the container, and meansproviding for relative axial movement without turning between the stem and the plunger.
